V IMACHINE FOB, SEPARATIIIG STICKERS 01\l' THE OPENING FLOORS OF TIN lVIILLS,

T0 aZZ whom it may concern.-

Be it known that I, Josnrnr CARL TIMBER- LAKE, a citizen of the United States, residing at 822 Market Street, in the city of Wheeling, in the county of Ghio and State of West Virginia, have invented certain new and useful Improvements in Machines "for Separating Stickers on the Opening Floors of Tin Mills, of which the followlng is a specification.

My invention relates to improvements in machines for separating sheet metal plates or stickers as they are called and the object of the invention is to device a ma chine whereby the plates or stickers, which adhere after being rolled and cut, may be separated without difficulty and without liability of spoiling the sheet.

A further object is to dispose with all troublesome handwork and the waste incident to such work.

My invention consists of a pair of rolls journalled in suitable bearings, suitably driven, a pair of flaring guides suitably supported in the frame and extending towards the tangential point of the rolls, and beaters located between the flaring guides suitably driven, and designed to operate on the adhering plates as they are pulled through the rolls.

Fig. 1 is a perspective view showing my machine for separating the plates or stickers.

Fig. 2 is a view of portions of the rolls, the guides, and the beaters, showing the plates or stickers being separated.

In the drawing like characters of reference indicate corresponding parts.

1 and 2 are the rolls of my machine which are journalledin suitable hearings in the bearing frames 3 and 4:.

The rolls are shown driven throughgearing from the electric motor 5.

6 and 7 are flaring guides suitably held in the frames 3 and 4.

8 and 9 are spindles journalled in suitable hearings in the frames 3 and 4. The spindle 9 is driven by an electric motor 10 and communicates motion by means of the pinions 11 and 12 to the spindle 8.

13 and 14 are beaters located respectively on the spindles 8 and 9.

15 and 16 are the sheet metal plates which are designed to be separated. The plates are drawn through the rolls by the pressure of the rolls on them and in the direction in= I Specification of Letters Patent. Patented Aug. 29, 18 22. Application filed. January 24, 1921. Serial No. 439,640.

dioated by arrow and are separated by the beaters 13 and 14:. I I

Previous to my invention it has been diflicult to separate the sheets or stickers after they have passed through the hot rolls and have been folded and cut by shears into sheets. The cause of the adhering of the sheets together it is not necessary here to account for, but it is well known that pre vlous to my invention laborers had great difliculty in separating these sheets by hand with hatchets or sharp instruments. Often in their efforts to separate the sheets they would knock a hole in them and thus spoil the sheet. In their case it would be possible to separate the sheets for a certain distance but no further and thus the sheets would have to be scrapped.

It will be understood that the beginning of the separation has still to be made by the laborer but he has only to separate a corner or just enough so that the beaters can be placed between the sheets and the corners or edges caught under the rolls when the plates or sheets can be pulled through by the pressure of the rolls and separated by the beaters.

It will be seen from this description that I provide a very simple device saving time and labor and at the same time insuring the effectual separation of the plates 01' sheets with a minimum loss of time and material.

l/Vhat I claim as my invention is:

1. In a sheet separating apparatus, the combination with sheet pulling rolls of revolving beaters arranged to operate between the sheets to separate the same.

2. In a sheet separating apparatus, the combination with sheet pulling rolls, of revolving beaters arranged to operate between sheets of a pack to separate the same, and guides between which the heaters are positioned.

3. In a sheet separating apparatus, the combination with sheet pulling rolls spaced apart to afif'ord a passage between them of revolving beaters located on opposite sides of the plane-of the passage and designed for interposition between partially separate sheets of a pack to complete the separation oflithe sheets as they are drawn between the ro s. I

4:. An apparatus as recited in claim 3, including guide members between which the heaters are positioned, said guides being inclined with respect to both the beaters and the rolls.

5. A sheet separating apparatus comprising frame members, pulling rollers extending between said frame members and supported thereby, said rolls being spaced apart to afiord'a passage between them, revolving shafts extending between said frame member at one side of said rolls and approx1- mately opposite said passage, beaters car ried by said shafts for interposition be tween partially separated sheets of a pack supported thereby.

In testimony whereof I aflix my signature. V
